Michael G. Schwern 280ad88aa0 git-svn: factor out _collapse_dotdot function
The SVN API functions will not accept ../foo but their canonicalization
functions will not collapse it.  So we'll have to do it ourselves.

_collapse_dotdot() works better than the existing regex did.

This will be used shortly when canonicalize_path() starts using the
SVN API.
